Influence of glyphosate tank-mix combinations and application timings on weed control and yield in glyphosate-resistant soybean. weeds listed in the table below: 1 quart per acre grass and broadleaf annual weeds less than 6 inches in height or circumference and vines less than 3 inches in length. Ensuring weed height does not exceed six inches is probably a good estimate for the beginning of the critical period in many situations (Bradley et al. Lower rates will result in reduced performance. marestail/horseweed, morning glory, kochia (dicamba only), wild buckwheat (Tordon 22K only); 12"cocklebur, lambsquarters, pigweed, Russian thistle (2,4-D only). A. Scott, D. A. Mortensen, D. D. Calvin, H. D. Karsten, and G. W. Roth. Ten weed species in the U.S. are known to have glyphosate-resistant populations and the populations of tolerant species are likely to be increasing. *This product is not registered in California or Arizona for use in mistblowers. Leaf surfaces also consist of an uneven epicuticular wax that serves to further reduce contact between water droplets and the leaf surface (Figure 1). This product moves through the plant from the point of foliage contact to and into the root system. It is generally non-selective and gives broad-spectrum control of many annual weeds, perennial weeds,woody brush and trees. 2023 Corteva. Early post followed by late post glyphosate has also been observed to produce higher grain yield compared to a single application (Gower et al. Coverage of the top one-half of the plant is important for best results. Pour rinsate into application equipment or a mix tank or store rinsate for later use or disposal. Applying larger Selective Equipment If an emulsifiable concentrate formulation is used, premix one part emulsifiable concentrate with two parts water, and add the diluted mixture slowly through the screen into the tank while continuing Finally, the strongest glyphosate solution.

When using application methods that result in less than complete coverage, use a 5-percent solution for annual and perennial weeds and a 5- to 10-percent solution for woody brush and trees. per gallon = 0.375 gallons per acre or 1 quarts per acre (0.375 x 4) or 3 pints per acres (0.375 x 8) Example 7b You have calibrated a 300 gallon sprayer. Use the following equation to convert from a broadcast rate per acre to a band rate per acre. Due to earlier planting and more rapid vegetative growth, corn typically does not benefit from reduced row spacing. Clay, S. A., J. Kleinjan, D. E. Clay, F. Forcella, and W. Batchelor. Colorants or marking dyes may be added to spray solutions of this product; however, they can reduce performance. Of particular concern for polar herbicides such as glyphosate is the non-polar nature of cuticle-associated waxes. Making applications at the IF IN EYES Hold eye open and rinse slowly and gently with water for 15 - 20 minutes. This cloud can move in unpredictable directions due to the light variable winds common during inversions. 2003) by reducing the competitiveness of weeds (Hock et al. altitude and are common on nights with limited cloud cover and light to no wind.

Still, yield loss can be large and careful attention to weed removal timing by producers will help maximize soybean yield. For best results, spray coverage should be uniform and complete. The standard rate of glyphosate is 0.75 lb a.e. I'll take a practice run with the atv to see how long it will take. Spray coverage should be uniform and complete. Do not induce vomiting unless told to by a Poison Control Center or doctor. When handlers use closed systems, enclosed cabs, or aircraft in a manner that meets the requirements listed in Worker Protection Standard (WPS) for agricultural pesticides [40 CFR 170.240 (d) (4-6)], per acre. NOTE: Local terrain can influence wind patterns. Smoke that layers and moves laterally in be avoided when wind speeds are below 2 mph due to variable wind direction and high inversion potential. In these instances, repeat treatment may be necessary. Use caution to avoid siphoning back into the carrier source. If you can measure these three things, then you can calculate how much water you will use to spray an acre. . it is alot easier to just say 1 to 2 qts per acre, applied with 12 to 24 gallons of water. Check Morningglory species and wild buckwheat are among the most tolerant. begins to drip. One method for adding other herbicides into a continuous Roundup Ready system is to rotate to other Roundup Ready crops. Tank mixtures with 2,4-D amine formulations may be applied by air in California for fallow and reduced tillage systems, and for alfalfa and pasture renovation applications only. If such symptoms are observed, provide the animal with plenty of fluids to prevent dehydration. Poor field performance of glyphosate can be attributed to a number of environmental conditions or management decisions. {{wg.store.city}} Active Ingredients: Glyphosate.

Therefore, any environmental condition speeding the drying of spray droplets on a leaf surface will reduce absorption. Since their commercial introduction in the U.S. in 1996, herbicide-tolerant crops have been widely and rapidly adopted (USDA-ERS, 2010). Most often the critical period begins a couple of weeks after crop emergence. Although little glyphosate is absorbed through stomata, reduced CO2absorption lowers photosynthetic rates, translocation, and thus absorption. When making applications in low relative humidity, set up equipment to produce larger droplets to compensate for evaporation. Do not allow the herbicide solution to mist, drip, drift or splash onto desirable vegetation since minute quantities of this product can cause severe damage or destruction to the crop, plants or other areas Equivalent to 356 grams per liter or 3 pounds per U.S. gallon of the acid, glyphosate.

If it's plan 41% I'd go 2 oz per gallon on water and throw in about 10 oz of dawn dish soap with 16 gallons. Figure 3. Since foliar-applied herbicides move by simple diffusion, maintaining a high concentration gradient improves absorption. No pesticide in history has been sprayed so widely. Apply this product during fallow intervals preceding planting, prior to planting or transplanting, at-planting, or preemergence to annual and perennial crops listed in this label, except where specifically Conversely, low weed density and diversity, well-fertilized corn, and ample rainfall will shorten the critical period. This Velvetleaf stressed by drought or flooding had much greater glyphosate tolerance than non-stressed plants. causing serious personal injury, if ignited by open flame, spark, welder's torch, lighted cigarette or other ignition source. I'd then wait 2 week for the new stuff to start to grow. Then wash thoroughly and put on clean clothing. 2. Degradation of this product is primarily a biological process carried out by soil microbes. The maximum use rates stated throughout this products labeling apply to this product combined with the use of all other herbicides containing glyphosate as the active ingredient, whether applied as mixtures or separately. AVOID DRIFT. 2003. Make application when the To Non-selective, broad-spectrum weed control for many agricultural systems and farmsteads. When spraying, avoid combinations of pressure and nozzle type that will result in splatter or fine particles (mist) that precautions regarding crop injury. Foliar-applied herbicides such as glyphosate have the advantage of avoiding the soil environment where colloids, mineral nutrients, and microorganisms can greatly reduce herbicidal activity. Limited to stock on hand. Best control of most perennial weeds is obtained when treatment is made at late growth stages approaching maturity. a.e product (Roundup PowerMax) to get the same amount of glyphosate acid.
